I read the book a few years ago and thought it was pretty good entertainment reading--suspenseful and exciting. People took it too seriously, but the author was partly to blame for that, considering his statement at the beginning of the book about "facts" he'd included. I wasn't very excited to see the movie (obviously I didn't rush out to see it), but it turned out to be better than I thought it would be. I was surprised that it was fairly slow-moving, possibly even less suspenseful than the book. It wasn't great but not bad.
